Trimmer for grass stalls when opening air. Why stall the lawn mower at a load

Why stalls a lawn mower or a lawn mower when pressing for gas, opening an air damper or at high speeds

If the check of the ignition system, fuel filters, muffler did not give tangible results, the tool still does not want to work normally at minimum speeds, you need to check the carburetor.

To adjust the operating modes on the device housing, there are three screws designed to set the minimum rotation speed, maximum revolutions and idle speed.

On many models, manufacturers install only a blanket adjustment screw to avoid incompetent attempts to adjust the device. In all variants of the device, adjustment must be performed exactly according to the recommendations of manufacturers.

If the adjustment of the device has not led to the restoration of the normal operation of the tool, it is necessary to carry out a complete disassembly of the device with inspection. It should be understood that the carburetor is a rather complicated device, in the absence of experience it is advisable to contact specialists.

When disassembling it, it is important to carefully examine and rinse all the nozzles, air and fuel channels, a filtering grid. Damaged elements must be replaced with new

The nozzles must be cleaned with a soft wire of the corresponding diameter.

It is advisable to perform work under the appropriate conditions. The carburetor contains many small details, the loss of any of them will make the device inoperative.

Classification of engines malfunctions

Before starting the chainsaw, it is necessary to check the condition of the saw part, season the fuel and oil tanks. After checking, proceed to launch. If there are deviations or failures in the drive, it is necessary to carefully examine the saw engine. As a result of an external inspection, verify the completeness and integrity of all nodes, the absence of mechanical damage, fluxes of gasoline and oil. We indicate the main malfunctions associated with the poor operation of the engine:

• The engine does not start.
• Starts up, but soon stalls the chainsaw.
• It works unstable.
• Ceases to function at a load.
• Loses his power.

Search for engine malfunctions is carried out in the following main directions:

Saw mechanisms need constant care, prevention and repairs.

Knowing the principle of action of a two.stroke gasoline engine will help the operator to independently determine the cause of the refusal and quickly restore the gas.speaker work.

What could break

Malfunctions with a benzocosa associated with the fact that this device is not started, in a certain way are classified by specialists of service services. They stand out malfunctions with the following nodes of the mechanism:

• the engine in which the piston and bearings can be worn out or fail to crack the crankcase;
• the fuel supply system, while it is possible to clog the filter or problems with the carburetor;
• mechanical damage to wires, tubes, hoses;
• The ignition chain.

To correctly determine the knot where the breakdown occurred, it is necessary to pay attention to the circumstances of the trimmer stalls for the grass.

Ways to eliminate breakdowns

Subsequent work is likely on the carburetor:

• cleaning and adjustment of the fuel supply valve;
• similar work with a valve producing redesigned gases and pairs (after burning fuel);
• replacement of the spring more weak on the entrance valve;
• restoration of the tension of the carburetor cable;
• replacement of the fuel leaks hose, verification and strengthening of a weakened connection;
• changing the rotor damper disk;.
• Change of faulty wire or ignition coil.

Immediately after the start

Smelting Motokos or a trimmer for the grass after starting is justified by subsequent reasons:

• impressive of previously adjusted valves;
• first the wrong settings of the valve mechanism;
• clogging with deposits of the fuel supply valve;
• the hose is worn or poorly annexed.

Due to the violated method of injection of a fuel, a lawn mower or a trimmer for grass is very vibrated in work.

Not starting a chainsaw on hot

There are no unnecessary phrases in the operating instructions, everything that is proposed is aimed at the trouble.free operation of the lawn mower. Cleaning all parts after each cycle of work contributes to the light removal of not hardened residues and dirt. You need to clean only cooled nodes. This technique contributes to the quality of the air cooling of the engine and the gearbox.

For refueling, it is necessary to use fuel with oil recommended in the instructions. If you leave the combustible mixture in the fuel tank, the oil will float and dies on the damper when starting, worsening its adjustment. The mixture can give a sediment and score fuel supply in the carburetor.

When preserving equipment for the winter, make an audit, grease the gearbox and the piston system, wrap the entire saw in the oiled rags and store in a dry place.

It is impossible, dangerous for the instrument and health of the mowing, use a metal cable instead of fishing line. It cuts more efficiently, but the load on the gearbox and the engine increases.

Carburetor adjustment and configuration

The maximum and minimum engine speeds, even idle is regulated by the carburetor. The stable operation of the lawn mower depends on the amount of fuel mixture and air. The lawn mower is not started with disturbed adjustment of the carburetor. The procedure for setting up the device for supplying fuel at low speeds (L), high speeds (H) and idle (T) is regulated by the same vints:

• The chainsaw should work for at least 10 minutes, since the adjustment is carried out in hot.
• The screw n is flooded smoothly to maximum speed, then turning on ¼, counterclockwise, reducing the speed of rotation of the engine shaft.
• The idle stroke is regulated by the screw T, ensuring that the braid for the grass does not rotate.
• The screw l is regulated, first opening the throttle as much as possible, and then smoothly reducing the speed to stable minimum.

After adjustment, a proper carburetor with cleaned filters should ensure the operation of the engine. In the event of a malfunction of the carburetor, after its repair, it will again need to configure the supply system before starting the lawn mower.

Rare breakdowns that prevent the operation of the lawn mower can be:

The most important malfunction, the elimination of which is associated with the replacement of the engine may be the failure of the piston group of the engine. The cost of repair will cost about 70% of the cost of the product. To figure out the reasons why the lawn mower is not starting up will help

The gasoline trimmer for the grass starts and stalls

Why is a trimmer not starting for grass gasoline? Reasons and their elimination

Recently, a gasoline trimmer for grass has acquired the status of one of the main tools in the arsenal of summer residents. And this is not surprising, because a motorized braid for grass allows you to quickly put a personal plot in order. However, sometimes it happens that the trimmer for the grass does not start hot and even on cold. In such situations, you have to independently establish the cause of the malfunction. Let’s find out what to do if a trimmer does not start for grass. The reasons that most often lead to such troubles will be considered further.

The trimmer for grass stalls. how to eliminate the problem

A gasoline trimmer for grass is a useful tool for cleaning from unnecessary grass of house territories and large area lawns. The design of this technique is quite complicated, therefore, if the device breaks, there may be several reasons. The most likely factors that have caught a breakdown are usually described in the user guide. Knowing why a trimmer for grass stalls, you can try to independently eliminate the defect. The most common malfunctions provoking the motorcycle stops, and the ability to repair them with your own hands is in the material further.

In order to most accurately determine the cause of the trimmer malfunction for grass of any brand (for example, echo) and find out the possibility of eliminating it, you need to install, when performing what action the device stalls. The engine can turn off both at idle and at high speeds, heated under load or immediately after starting and t.D.

If you stalled after gas supply

Owners of gasoline braids often mention that the lawn mower stalls when you press the gas. Usually such a breakdown occurs due to problems in the carburetor. A failure in his work can occur due to long-term storage, use in difficult conditions, significant overload of the motor. The symptom of such a breakdown will be vibrating movements of the device during operation.

On a note! Users familiar with the repair of a car carburetor can try to restore this important node of the trimmer for the grass on their own, using the instructions for operating. Otherwise, the correct decision will be to seek help from the service center representatives.

Sometimes a trimmer for grass stalls when you give gas because the fuel valve is clogged. This interferes with the supply of gasoline. To eliminate the problem, it is enough to loosen the valve. Thus, normal supply of carburetor fuel will be restored.

Another possible reason why the lawn mower stalls when gas is supplied is pollution of the soundtress (check valve). This detail prevents the appearance of a vacuum in a gas tank. If it is clogged, the air does not flow, which means that fuel does not go to the carburetor. To eliminate the problem, it is necessary to clean this element.

If it stalled at high speeds

If the carburetor stalls at high speeds, this means that in idle and small there are enough incoming fuel, and to work on high is not enough. Then it is necessary to check the serviceability of the following nodes of the trimmer for the grass.

• Fuel hose. its integrity could be violated as a result of cracking. In this case, you need to replace the part. Or maybe you just need to tighten the clamps.
• A filter network between a carburetor and a hose for supplying a gasoline mixture-it could clog. In this situation, it is necessary to clean the detail.
• The valve on the gas tank cover. he could stick or clog with garbage. Cleaning is also necessary.
• Carburetor. perhaps as a result of constant vibration, it was resolved. This is usually characteristic of cheap Chinese details. To eliminate the problem, it is necessary to set up according to the instructions. In some cases, it is enough to only weaken the tightening of the carburetor case. If the adjustment is not possible, it is necessary to install a new element.
• Additionally, check the air filter. Perhaps it will need to be washed and cleaned or replaced with a new one, as he could clog with dirt and particles of grass when tilted technology, when the user mowed in hard.to.reach places.

If you stalled during work idle

If the lawn mower stalls, working idle, there may be several factors reasons.

• First you need to check the prepared fuel solution, when it comes to a four-stroke trimmer working on a gasoline-oil mixture. There is a chance that it is made incorrectly. the proportions are not withstanded. Because of this, the gearbox is warming up, and the revolutions on the drum are lowering.
• Another probable cause is blockage of elements such as a throttle, air filter or carburetor. You need to clean the indicated details.
• Another possible factor is to resolve or incorrectly carried out carburetor adjustment. You need to adjust the setting according to the instructions.
• Observe this problem mono and when opening the air damper. In this situation, the lack of fuel for a trimmer for grass occurs through the fault of the air flow.

If the device does not have enough fuel, it works properly at high speeds or when they increase, but stalls at idle. If the root of the problem consists in the carburetor, the lawn mower will be disconnected both with cold startup and hot.

If you stalled after starting

If the technique starts and stalls immediately after starting, this indicates the wrong settings or deducting the device. As a result of this, the fuel enters the engine unevenly, which leads to significant vibration and disconnecting the trimmer for the grass. To fix the breakdown, it is necessary to reconfigure the device according to the user management.

Another probable problem is the blockage of the valve supplying the gasoline mixture. It must be cleaned.

On a note! If the trimmer for the grass starts, but immediately stalls, it may also mean that the fuel is moving to the carburetor with difficulty. Weakening the valve will help to eliminate the problem. this will provide uniform and free circulation of fuel in the device.

Another possible reason is the damaged fuel intake hose. Air can penetrate through cracks and holes into the system. To solve the problem, you need to increase the engine speed in order to get rid of air bubbles that have penetrated the device.

If you stalled when opening the damper

If the technique works properly at idle, but stalls when opening an air damper, this reports about the penetration of air into the system through cracks in the fuel supply hose or damaged oil seals. To fix the breakdown and establish the work of the tool without driving air from the atmosphere, it is necessary to replace damaged parts.

Preventive measures and operating rules

So that the lawn mower does not work and does not stall when starting, it must be correctly stored and operated. Compliance with the following simple recommendations will forget about problems.

• When begging the grass, you need to monitor the state of the cooling system. It is also necessary to regularly clean the channels in the case and starter’s ribs.
• To clean the tool, you should use kerosene, solvent, or other washing tools.
• You can not clean a hot tool. it must cool before washing.
• It is important to observe the recommended working mode. this will avoid overheating of the engine.
• If a braid for grass is not used over the next thirty days, the fuel must be drained, otherwise it will fall into heavy components that can score the channels of the carburetor.
• After the fuel is merged, the trimmer for the grass should work at idle for some time until it turns off. This will allow you to completely get rid of the rest inside the working mixture.

To store the tool in cold weather, you need:

• completely drain the fuel;
• disassemble the lawn mower, wash and clean all available components;

• inspect the condition of the parts, eliminate all defects that can be corrected;
• pour the required amount of oil into the gearbox;
• Clean the air filter;
• perform partial disassembly of the engine, wash all moving parts, blow and lubricate thoroughly;
• To lubricate the piston, unscrew the candle, then raise the piston to the upper dead point by the starter, pour a small amount of oil into the hole for the candle and do the crankshaft several times.

Important! If there is no way to store a trimmer for grass in a warm dry room, you must first wrap the motor with an embarrassed rag.

Only by observing these rules, you can be sure that the lawn mower will work properly and will not stall for a number of seasons.

As you can see, stopping the work of a trimmer for grass can be caused by many reasons. Most of them can be fixed independently using the user instructions. In cases where there is no self.confidence, the equipment is recommended to be attributed to repairs. It is worth remembering that incorrect actions can cause even greater harm to the trimmer. As a result, the repair of Motokos will cost a much larger amount than it would be initially, and in the worst case, it may be necessary to buy a new unit.

What could break

Malfunctions with a benzocosa associated with the fact that this device is not started, in a certain way are classified by specialists of service services. They stand out malfunctions with the following nodes of the mechanism:

• the engine in which the piston and bearings can be worn out or fail to crack the crankcase;
• the fuel supply system, while it is possible to clog the filter or problems with the carburetor;
• mechanical damage to wires, tubes, hoses;
• The ignition chain.

To correctly determine the knot where the breakdown occurred, it is necessary to pay attention to the circumstances of the trimmer stalls for the grass

At high speeds

The hole in the fuel cover (saepun) of a trimmer for grass

With a similar problem, it is worth paying attention to the fuel valve, which, when clogging, ceases to normally pass the fuel mixture. By solving this malfunction, it is weakening using a suitable tool

In addition, the problem with the circulation of the fuel mixture may cover in the contamination of the valve. To do this, just blow it with a stream of compressed air.

• etching of atmospheric air into the combustion chamber;
• problems with the circulation of a mixture of fuel;
• clogging the saapun in the lid of the fuel tank (cleaning the hole with a thin sewing needle);
• Incorrect carburetor adjustment.

When air sunses, when I operate ICE, it is necessary to check the tightness of the pipes and the integrity of the gaskets in the CPG. The problem with the circulation of the fuel mixture can be solved by the elimination of blockages in the fuel pipes leading to the carburetor. If a vacuum occurs in the tank and not receipt of the fuel mixture to the carburetor, it is enough to clean the soundtress with a thin needle and blow it with air.

If the lawn mower stops when pressing the gas, then the reasons may be the following.

• The most common option is a fuss of adjusting the carburetor, which occurs with significant loads on the drive, after a prolonged inaction of the mechanism or when it is used in severe conditions.
• The clogging of the fuel valve, which eliminates it with the message, as a result of which gasoline according to the system begins to flow normally.
• The weakening and hanging of the cable in the carburetor. Also, a tensile of the fuel hose can occur up to its rupture, caused by the action of a significant load.
• Clogging of the saapun (check valve), as a result of which fuel does not enter the tank.

If the problem is associated with the carburetor node, then it can be recognized by the appearance of vibrations of the lawn mower. Когда лопается шланг или растягивается трос — выполняют замену данных комплектующих.

When a braid for grass stalls at high speeds, this is due to the following problems:

• clogging or clutching a valve located on the gas tank lid;
• The carburetor was diluted under the influence of vibrations arising during the operation of the mechanism;
• problems with the circulation of the fuel mixture;
• atmospheric air
• The hose intended for fuel fuel cracked or slightly connected.

The carburetor is regulated by relying on the operational instruction to the trimmer. For configuration, it is often enough to weaken the tightening of its body. If there are problematic issues with the circulation of the fuel mixture, then it can gradually enter the carburetor. After its production, the engine stalls at high speeds.

• a clogged air damper;
• The clogged filter is fuel, and when you give gas, this is especially noticeable;
• the air of the crankshaft shaft occurs;
• damaged gasket between the cylinder and the carb.

When you cleared, washed and blowing the elements, but again the lawn mower stall when you press the gas-replace them with new ones, check the quality of the fuel, as well as the literacy of the proportions of the cooked mixture. When opening the air damper, the tool will stall for the following reasons:

• Dosage carburetor.
• The appearance of cracks on the fuel hose caused air leaks.
• The occurrence of problems with the oil seals.

In the process, situations arise when the lawn mower at high speeds is subject to a similar sharp stop. It occurs for the following reasons:

• due to problems with the circulation of the fuel mixture;
• with air leaks;
• The fuel intake hose is poorly connected or cracked and cannot be used;
• stab or clogged the valve of the cover of the gasoline tank;
• The carburetor was resolved.

If you stalled when heated

The lawn mower often stalls when heated. It looks like this. the tool starts, works “jerking” (not smoothly) and stalls quickly. This situation occurs due to boiling of fuel in a carburetor or incorrectly selected damper, which should not be disk, but rotary. In the latter case, if an error is detected, the part must be replaced.

The reason for heating the trimmer for the grass may be damaged ignition circuit or faulty coil. The broken node will need to be replaced with a new.

At idle

At single speeds, the common reasons for stopping a trimmer for grass are as follows:

• reducing the speed of the gearbox when heating it, which is a consequence of the use of inappropriate fuel mixture;
• clogging of the throttle;

If a carburetor is a problem place, then the technique will stop at the “cold” and with a “hot” launch.

Diagnosis of malfunctions

The user first needs to check if there is a fuel in the tank. Starting in agreement with annotation, putting the saw on the side. Set the air damper to the position “Closed”, pump up fuel, turn on the ignition and produce 3-4 sharp jerks by the starter. If the engine has earned, open the air damper. The lawn mower is not started. we repeat the operations with a slightly open air damper.

The lawn mower cannot work for a long time. Gearbox and engine will overheat. Mowing less than 15 = 20 minutes, taking a five.minute break. In hot noon, the operating time is reduced by half. When mowing weeds, sedgers, the working hours are required to reduce.

If you are unsuccessful, we begin to find the reason for the refusal:

• check the quality of fuel;
• make sure the operability of the candle and the cleanliness of the candle canal;
• check the cleanliness of the air filter;
• Make sure that the fuel filter is not clogged;
• Check the cleanliness of the bastard;
• Clean the exhaust channel.

complex reasons will be detected in the diagnosis of a malfunction, leading to the overhaul of the carburetor. Such reasons include clogging of the internal channels of the carburetor, wear on it gaskets and violation of the tightness of internal halls with a vacuum loss. DIY lawn mowing repair, if it does not start, will require patience.

The gasoline trimmer for the grass stalls when you press the gas

Why is the chainsaw stall when you press the gas?

Hello! If you are on this page, then, apparently, your chainsaw stalls when pressing gas, and you want to know why this is happening and what to do with it.

Why does the lawn mower stall after starting? And Husqvarna sins. As a result, when pressing gas.

Well, I will try to help you with this problem, having examined the most common reasons for such an adversity, as well as methods for their elimination.

To begin with, I will immediately write for new users that many chainsaws before work requires the engine heating at idle for about one minute. Until the engine is heated, the saw can stall when gas is added.

So, if a heated chainsaw can work at idle, but stalls at a load, this means that:

• The carburetor is incorrectly configured or clogged. the most common case;
• She lacks air, the consumption of which increases sharply with an increase in revolutions. this means that the air filter is contaminated (the case is rare, since the filter pollution occurs gradually, so the user first notices power loss);
• She lacks fuel, the consumption of which also increases with an increase in revolutions. this means that the fuel filter (also an infrequent case) is contaminated;
• Well, the most unpleasant case, if there is excessive friction between the piston and the cylinder wall associated with the lack of oil in the fuel mixture. after such a chainsaw you are most likely, you will fly to the repair of the piston group, since bunches that prevent the piston and walls of the cylinder that impede the piston and walls of the cylinder work of saws.

Little oil in the fuel mixture

First we will analyze the most unpleasant case. Why? Because before you do manipulations with filters, it is better to make sure that your oil and gasoline are mixed in the correct ratio.

Here, however, it is worth noting that if your drank was already repeatedly (for ten times) has been opened by you, but continues to start, and then stall again with increasing speed, then with fuel, apparently everything is in order. Otherwise, she would just stop starting at all.

But still, I recommend that I immediately dispel the slightest doubts about the quality of the fuel, as soon as I drank you stalled when the revolutions for the first time.

Because if the cause is in fuel, then, as already mentioned above, you can get to expensive repairs. And so, it can still do.

Dispel doubts is to drain the old fuel from the tank and pour freshly prepared, in which oil and gasoline are mixed in the correct proportion.

The correct ratio is better to watch in the instructions for the saw. If you are lost, then we look at the ratio on the oil packaging. Usually it happens 1:50 or 1:40. If the oil is used “non.native” (well, for example, for the stihl “native” there will also be few Stihl), I recommend using a 1:40 proportion, even if 1:50 is written on the packaging with oil.

Trimmer for grass The lawn mower stalls when adding gas / Benzonase Trimmer Stalls When The Throttle

trimmer for grass The lawn mower stalls when gas added. trimmer for grass does not pull. Trimmer for grass loses momentum at load.

For an accurate dosage, I personally use a medical syringe and a measured capacity in which one liter of gasoline can clearly measure. I pour a liter of gasoline into a container, type in a syringe 25 (at 1:40) or 20 (at 1:50) oil cubes and add it to gasoline.

After preparing a new mixture, drain the previous mixture from the tank, in which we are insecure, and fill the freshly cooked.

Now that you have done everything to dispel any doubts about the quality of fuel, we proceed to further actions.

As I already wrote above, with a lack of oil on the piston and walls of the cylinder, scuffs can form. and almost always form. If you are lucky, and the bullys did not appear, then with a new fuel mixture prepared in the correct ratio, the chainsaw should begin to work normally.

If the bullying appeared, then the saw can start and stall several times, after which it will stop starting up. In such a situation, I sympathize with you, since, most likely, now you will need to make a replacement for a piston group that will cost a lot.

If the saw, as before, starts and stalls at high speeds, then we carry out manipulations with filters.

The air filter is contaminated

Moving in the contamination of the air filter is quite easy. You just need to remove it and start a chainsaw without it. if the saw works normally, then then the matter is in it and it just needs to be changed or washed, depending on its type. And do not be afraid that the chainsaw will work for a while without protection against dust. if there is no dust cloud around you, then everything is in order.

So, remove the air filter. Husqvarna ”and“ Stihl ”and ending with a click on gas, stalls on. To do this, you need to remove the lid from the back of the chainsaw, which is attached either with screws, or just with some kind of fixer that you just need to turn or jerk off.

If when the filter is removed after the drain, the saw works normally, then it means it is contaminated.

Air filter is felt or nylon. The first resembles cotton wool or synthetic winterizer, and the second looks like a small mesh of nylon threads stretched on a plastic case. The gasoline trimmer for the grass does not start? Reasons and solutions on the example of Elitech T750. The felt should be changed to a new one, but the nylon can simply be washed in soapy water, dried and put in place.

Well, then we calmly use the chainsaw.

The fuel filter is contaminated

If the option with an air filter did not suit you, then try to change the fuel. It is located in a gas tank and attached to the hose through which fuel is taken from the tank.

Why is the Stihl 180 stall when you press gas or at idle, in full swing

Any tool is able to break and the stihl ms 180 chainsaw is not an exception. Today we’ll try to understand such issues as: why the chainsaw stalls with increasing speed, as well as at idle and at full. Consider the options for diagnosing and eliminating faults associated with this behavior of the Stihl 180 chainsaw.

Опытный электрик слил в сеть секрет, как платить за электроэнергию вдвое меньше, легальный способ… Читать далее

Why is the chainsaw stall when you press the gas

Suppose a chainsaw work normally at idle, but with a sharp press on the gas stalls. What could be the reason? It is immediately clear that the matter is not in the ignition (lack of spark), t. to. If the ignition is malfunction and the lack of a spark, the tool would simply not start. So the fuel system remains.

There are a lot of malfunctions of the fuel system and to determine the exact reason why the Stihl 180 chainsaw is stalling when the gas is pressed, it is necessary to carry out its full diagnosis. We recommend reading about the common malfunctions of the Stihl 180 chainsaw and their elimination.

Checking the filter

The first thing you need to check is the fuel filter.

In some cases, a filter clogged with dirt, it is unable to pass through the fuel mixture through sufficient quantities.

Accordingly, a deficiency of fuel occurs in the system, which leads to the fact that when pressing the gas is pressed, the fuel burns out, and the new one still does not have time to act as a result of which the Stihl chainsaw is stalling.

Also, with a clogged fuel filter, there may be a noticeable drop in the power of the chainsaw at maximum speed, but this is with slight contamination.

Air filter

On the pages of the World Wide Web, you can find information that the chainsaw of the Stihl 180 can stall due to severe air filter pollution.

I would like to refute this not entirely correct information, and report that the STIHL carburetor MS 180 is equipped with a compensator, which is designed and installed in order to make the air of the STIHL 180 chainsaw, bypassing the contaminated air filter.

Of course, the power with a clogged air filter will fall a little, but it will definitely not stall. Another capacity may fall due to the wear of the piston, here the repair of the piston chainsaw of the Stihl MS 180 will already be required.

Carburetor

One of the reasons why the chainsaw does not develop momentum when pressing gas, but on the contrary, stall, these are malfunctions of the carburetor. Suppose the STIHL 180 saw worked properly, and then it was put for a long time and did not use it.

After it was brought up, and it works well on idle, and when you press the gas, it can stall. Why stalls? The reason for the sticking valve-comps of the carburetor. Of course, this is not 100%, but the probability of such a malfunction is high.

We recommend reading an article about the device and repair of the STIHL 180 carburetor.

In order to check the nozzle, you need to remove the carburetor and disassemble it. To remove, it is necessary to unscrew two nuts of fastening of the air filter and carburetor, and then remove the air filter and the engine control lever, disconnecting the air damper control traction from the carburetor. Next, you need to pull the carburetor a little on yourself, and disconnect the fuel supply hose.

Having removed the carburetor, it needs to be blown and cleaned of dirt, only after that the carburetor can be promoted.

It is necessary to promote the cover of the main camera of the carburetor, this is the one on which a compensator is installed on top. Further with a bolt by 8 mm and a length of at least 50 mm. We knock out the valve.

After the nozzle is removed, you can blow it with a compressor. The valve must pass air in only one direction, if you can freely blow the valve in both directions, then it is faulty and it is necessary to replace it with a new. Assemble a chainsaw after the valve is repaired, it is necessary in compliance with the reverse sequence of disassembly.

Look clearly how the carburetor repair is repair, or rather how to correct the valve record from the carburetor case, you can watch the video.

Another frequent reason why the saw can stall with an increase in revolutions, air leaks to the carburetor.

It is possible to check this only by having a special tool, but it is worth noting that if preventive work with the carburetor has not been carried out for a long time, then you can install a new set of gaskets in the carburetor. In some cases, this helps to solve the problem with its depressurization.

Disassembled the carburetor to replace the gaskets, you need to carefully inspect its needle valve, press the rocker and control its raising.

Sometimes, especially after the stihl chainsaw stood for a long time with fuel in the carburetor, the needle can burn to the carburetor body and not perform its functions.

Simply put, the needle valve will not pass the fuel mixture. In this case, the saw will not work.

Why stalls idle

The first and most common cause of this malfunction is the wrong carburetor adjustment. You can adjust the idle speed yourself, for this you need to have a STIHL adjustment screwdriver, which comes with the unit. The adjusting hole is located on the right side of the STIHL 180 saw on the handle and is indicated by the symbols “-” and “”.

If the Stihl chainsaw does not hold turns and stalls at idle, you can almost 90% be sure that it has violations in the system of the fuel pump, as a rule, it is an air leak into the crankcase through the lining of the pallet, or, much more often, through the seals crankshaft. The air leaks reduces or even completely stops the impulse, which is supplied through special channels to the fuel pump of the chainsaw. As a result of this, the Stihl 180 chainsaw does not receive the required amount of fuel and stalls at idle.

Diagnose, you can use a special device called a vacuummeter.
